phaser for long thin molecule
by Ursula Schulze-Gahmen 08 Feb '13

08 Feb '13

I am doing molecular replacment for a very elongated molecule in phaser. I would like to try different values for the maximum patterson cutoff but I am not sure which parameter I need to change in the phenix version of phaser. Does somebody have experience with this? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

How to model domain-wide disorder in Phenix.refine (turn off bump interactions) ?
by Phil Jeffrey 08 Feb '13

08 Feb '13

Hi, I've got a pernicious problem where the electron density for one domain appears to extensively interpenetrate another similar domain. I'm in the process of trying to work out things like: MR solution in the wrong space group courtesy of pseudo-centering. In the meanwhile I want to model it as interpenetrating domains, and need to turn off VdeW bumps at the domain (chain) level of structure. I can't just model it as a infinite list of alternate locations. I (think) I remember how to do this in CNS (constraints interaction), but is there a way to do this in phenix ? I could not track down a particularly promising section of either the manual or the .def/eff file(s). Thanks Phil Jeffrey Princeton

Designing heavy atom positions on my DNA crystal
by Xiang Li 07 Feb '13

07 Feb '13

Hi everyone, I am trying to grow my DNA crystal with bromide derivatives. The content in one asymmetric unit is a 30 bp DNA duplex. I am considering about how many bromides modified bases should I use to ensurethe strong enough heavy atom signal. Also where to put these bromides? To my understanding, maybe I should put the heavy atoms at the most rigid places, avoiding the clashes and not too close to other heavy atoms. I have few experience on this and hope you could give me some help on the design. Thanks a lot! Sincerely, Xiang

Phaser annoyance
by Morten Groftehauge 05 Feb '13

05 Feb '13

Hi guys, The pop-up warning from Phaser about lack of eLLG for the resolution of the data would be more informative if you added the value of eLLG so one wouldn't have to scroll back in the log to find it. It would also allow the user to see with a glance whether the warning is because eLLG is under 120 or under 60. And it seems like the 'non-simple' Phaser GUI is broken in 1.8.2-1288. At least I haven't been able to open it, neither from the main window or by opening a previous job (Ubuntu 10.04). Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

AUTOBUILD: sequence file for multiple chains
by Gino Cingolani 03 Feb '13

03 Feb '13

Hi All, my model contains multiple chains and I would like Autobuild to build them all. What is the correct way to give multiple sequences (in FASTA format) to Autobuild? In my 'seq.dat' file, shall I leave one (or two) spaces in between one sequence and the other?

The source of the problem was in the stupid/silly category. I had left the "export" out. I didn't notice the problem since my test scripts didn't include the "-f" option, like yours, so they were reading the init scripts every time.

MR: Apply rotation and translation to structure factors
by Shweta Kailasan 01 Feb '13

01 Feb '13

Hello, I am trying to use a cryo-EM map as a MR model for an Xtal data set. I have calculated structure factors for my map using SFALL. And also used rotcross and trans.com (from AMORE) to determine best possible rotation and translation solutions. Is there is a program/script available that can be used to apply those rotations and translation to structure factors ? Most programs start with a coordinate file (pdb) as a model whereas my initial model is a map. I tried to use Phaser but it didnot work out. Any help would be highly appreciated. Thank you. -S <peter.ramsumair(a)credit-suisse.com>

Problem getting Phenix and Rosetta working together
by Dale Tronrud 01 Feb '13

Hi, I would like to get mr_rosetta running on my CentOS 6.3 64 bit computer but I can't seem to get them connected. I'm probably doing something stupid/silly but I'm stumped. I've downloaded, installed and compiled rosetta3.4 in the folder /usr/local/rosetta3.4. There are a bunch of files in rosetta_source/bin and they are executable. However, typing the following commands shows my problem. [dale@athena tln]$ echo $PHENIX_ROSETTA_PATH /usr/local/rosetta3.4 [dale@athena tln]$ ls -l $PHENIX_ROSETTA_PATH total 156 drwxr-xr-x. 10 root root 4096 Mar 20 2012 Antibody drwxr-xr-x. 3 root root 4096 Jul 26 2011 foldit-3.4 -rw-r--r--. 1 root root 1115 Mar 25 2012 new_apps.note drwxr-xr-x. 25 root root 4096 Mar 20 2012 protocol_capture -rw-r--r--. 1 root root 460 Mar 25 2012 README.Copyrights -rw-r--r--. 1 root root 12 Mar 25 2012 README.version -rw-r--r--. 1 root root 3345 Mar 25 2012 release.note drwxr-xr-x. 19 root root 106496 Mar 25 2012 rosetta3.4_user_guide drwxr-xr-x. 9 root root 4096 Mar 25 2012 rosetta_database drwxr-xr-x. 61 root root 4096 Mar 20 2012 rosetta_demos drwxr-xr-x. 11 root root 4096 Jan 30 15:27 rosetta_source drwxr-xr-x. 7 root root 4096 Mar 27 2012 rosetta_tests drwxr-xr-x. 13 root root 4096 Mar 20 2012 rosetta_tools [dale@athena tln]$ phenix_regression.wizards.test_command_line_rosetta_quick Skipping phenix rosetta tests: rosetta build not available.

Seats are still available for RapiData - the deadline is in 4 days for our course on Data Collection and Structure Solving at the NSLS.
by Robert Sweet 01 Feb '13

01 Feb '13

We will present RapiData 2013, the fifteenth offering of our popular course: Rapid Data Collection and Structure Solving at the NSLS: A Practical Course in Macromolecular X-Ray Diffraction Measurement The course will be held 21-26 April 2013: http://www.bnl.gov/RapiData/. Students could be at any level from advanced undergraduate to full professor. The course should accommodate 48 students total. We encourage all students to bring their own specimens for data collection, and to bring old data for the data-reduction and structure-solving tutorials. Please read the Course Announcement at http://www.bnl.gov/RapiData/. You'll see that many experts in the field will be available for lectures and tutorials. You'll find the application materials on the Course Application tab at this site. For the eleventh time we will hold a short lecture course on the fundamentals of crystallography for roughly five hours on Sunday 21 April. The body of the RapiData course really requires that students have a healthy knowledge of crystallography. For potential students who have some experience but are shaky about fundamentals, this course will help. There will be a small additional fee for the fundamentals course, to pay for Saturday night accomodations and food on Sunday morning and noon. Latin American Scientists: Several scholarships are available, from the International Union of Crystallography, to pay partial travel and subsistence costs for Latin-American students and junior faculty (under 40 yrs). Please apply for the course, and then contact R. Sweet (sweet(a)bnl.gov) if you are interested in applying for a scholarship. In accordance with the standards of the International Union of Crystallography, we observe the basic policy of non-discrimination, affirming the right and freedom of scientists to associate in international scientific activity without regard to such factors as citizenship, religion, creed, political stance, ethnic origin, race, colour, language, age, or gender, in accordance with the Statutes of the International Council for Science. At this course no barriers will exist beyond the application procedure that would prevent the participation of bona fide scientists.
